First-Timers-Only (FTO) - Please reserve this bug for a first-timer to work on as it should provide an easy introduction to the processes and tools for developing Open Rails.

Dave Nelson reports that the Menu > Options > Audio > % sound volume doesn't provide no sound at all - see http://www.elvastower.com/forums/index.php?/topic/30254-first-timers-only/page__view__findpost__p__219530

Also the tooltip shows the range as 0-100, but the control only allows 10-100.
The sound can however be silenced by setting the control "Sound detail level" to 0.

The manual does not explain what "Sound detail level" means.
The manual does not mention the control "% external sound heard internally"
The image in the manual is out of date.
